To all who??? it nuty concern.-

Be it known that we, EVERETT S. WOOD and J oNAs NORTHROP, citizens ofthe United States, and residents of Hopedale, county of \Vorcester,State of Massachusetts, have invented an Improvement inFilling-Exhaustion-Indicating Mechanism for Looms, of which thefollowing descri tion, in connection with the accompanying awings, isaspecification, like letters on the drawings representing like parts.

In order to positively control and efiect a change in the operation of aloom when the filling in the runnin -shuttle has become substantiaTllexhauste or Woven off to a predeterminec extent, variousinstrumentalities or mechanisms have been devised and put into practicaloperation.

The change in the operation of the loom may be the automaticstoppage-thereof to enable manual replenishment of filling to be made,or it may be the actuation of mechanism to automatically effectreplenishment of the running filling without stopping the loom.

Automatic filling replenishment may be effected by mechanism of theNorthrop type, as disclosed in United States Patent No. 529,940 andother patents, wherein a fresh supply of filling is insertedautomatically in the running shuttle of the automatically self-threadingclass without stopping the loom. Such looms are in extensive use, and wehave herein illustrated one practical embodiment of our invention inconnection with a loom of the Northrop type above referred to.

Our present invention has for its object the production of novel andeflicient mechanism to control and effect a desired change in theoperation of the loom when the running fillingis substantially exhaustedor Woven off to a predetermined extent, and, broadly considered, ourinvention comprehends purely mechanical control of the loom inccntradistinction to electric or electromechanical control.

In the present embodiment of our invention thefilling-exhaustiomindicating mechanism comprehends a mechanical feelerdevice governed and operated solely by or through means within theshuttle. the effective action of such device occurring when the runningfilling is exhausted to the'predetermined extent, taking place withoutcontact between the filling in the shuttle and anypart of the feelerdevice.

The feeler device comprehends two movable members, one of whichintermittingly impinges upon and is moved by means within the shuttleuntil the running filling is sub-. stantially exhausted, the secondmember,

up to that time inactive or passive, thereupon impinging upon othermeans within the shuttle and by such impingement becoming active andeffecting the actuation of the loom-controlling mechanism.

An actuator, as it has been termed hereinafter, is mounted on one ofsaid members and controlled by the other member, the actuator beingositioned inoperatively by the latter until t 1e predetermined fillingexhaustion is attained, whereupon the member becoming active operateswhile the actuator is operatively positioned and the desired change inthe operation of the loom is efi'ected.

As will appear hereinafter, there is no pressure upon the filling in theshuttle at the instant one of the members of the feeler device changesfrom passive to active condition a given forming-tool a constant radialdistance or difference in diameter is insured between the barrel or stepof the filling-carrier and its headthat is, the external diameters ofthe head and barrel will differ by exactly the same amount in any numberof bobbins finished by the same forming-tool or duplicates thereof.Consequently it is as accurate to feel between the yarn or filling onthe filling-carrier and the head thereof as between the filling and thepart of the carrier on which the filling is actually wound. This weutilize in the preferred embodiment of our present invention, as willappear hereinafter. There is great advantage, moreover, in employing afeoler device sult is attained+-vizi a feeler wherein the actuating oractive part or member nevercontacts with the filling, and especially insuch a feeler device which ef-. fect's'a change in the operation oft'he-loont immediately upon contact with some means within the shuttle,such as the filling-carrier o,r something pertaining thereto. i

The construction and operation of-our present apparatus is such thatpremature action is impossible, and a much desired rede'vioe dependingsolely on thefilling-carrier or means within the shuttleand 'at thesame time the structureis exceedingly simple and certain ineitsoperation. v i v I In our invention noadjustment is required, for therelative position between the impinging faces of the members of thefeeler device isin the first instance made and1adapt-' ed to theparticular-form of filling-carrier to 1' be used. Furthermore, itmatters notwhat shuttle is used, whether it be a little larger or alittle smaller or whether theshuttle 'is new or nearly worn out. 7

As will appear hereinafter, the relative forward position of the shuttlein the shuttleboxv and the position of the lay at the end of its forwardbeat have no effect upon the acobtainable.

. tion, arrangement, andoperation of our joined specification and.running shuttle being shown invention will-be fully described 'in'thesubparticularly pointed out in the following claims. g

As is usual in apparatus of thisgeneral character, the shuttle'hasa sideopening 1 to register with the openingl K in the front wall 2 of thefeeling or indicating shuttle-box 3, Fig. 1; i

The shuttle is shown ashavi'ng spring-j aws and in Figs; 1,4, and-5 wehave shown a compound carrier comprising a skewer '5, having rings onits-butt 6, and a bobbinhaving a barthe skewer and be held in positionby suitable catches 9, the jaws 4 engaging the rings on the butt 6. Itis to be understood, however, that this compound filling-carrier is notof I fner se, and so far as concerns its behavior in ejected therefromit diii'ers in no way from shuttle S, the controllingrjock shaftdto'efshuttle, the upturned armd fast on said rockconnections constituteloom controlling;

ationoffthe replenishing mechanism. The

' actuation ofsuch controlling means is effected by or through,filling-exhaustion-indicat rel 7 and a head 8- andadapterl to slip onto1 tion on theeline 8 8, Fig.1 ,taken' through the center of the feelermember} proper of the I feeler device, the parts being in normalposiinto position to be engaged bythe headof-the 4 (U engage and supportthe filling-carrier,

itself novel, nor do we make any claim thereto the shuttle or whentransferred thereto or the ordinary one-piece bobbin or filling-carrier.

The barrel 7 and head 8 are accurately formed by a tool of the preciseshape required, so that the difference in niameter between said parts isa constant quantity, and we avail ourselves of this fact in thatemboiiment of our inventionwherein the feeling action is between theyarn or filling and the head, as will appear.

The holiing-plate 10 for the shipper S" has at its outer end avertically-aajustable bracket 11, on which is secured a stand 12,preferably inclined at such an angle that the" feeler moves in a pathclosely coincident with the path of the lay A substantially as in ourprior patent, No. 789,472, dated May 9, 1905, and as shown in Fig. 2.Said stand is con veniently made in two parts bolted together andchambered out at 12*, Figs. 8 and 9, to receive a transverse andrectangular enlargement 13 on one member, termed the carrier, of thefeeler device forming a part of the exhaustion-indicating mechanism.

The carrieris made as a fiat elongated metal late 14, extending.rearwardly from the en argement or cross-head 13, a preferablycylindrical shank 15 extending forward from the latter and freelysliding through an opening in the front end of the stand 12.

The cross-head slides in the chamber 12 and is guided therein, a spring15*, coiled around the shank between the front end of the stand and thecross-head, acting to project or move the carrier rearward to theposition shown in Figs. 1, 4, 8, and 9, the rear end of the standlimiting such movement.

The body portion 14 of the carrier slides within a suitable opening inthe rear end' of the stand, and the rear end of the carrier is laterallyenlarged to form -a head 16, having a transverse impinging face or edge17..

Upturned parallel ears 1-8 are formed on the carrier, which latter islongitudinally out out at 19 from the cross-head to the ears, leaving atransverse bar 20 between their bases, and beyond the bar the carrier iscut out or apertured at 21. thehead being longitudinally recessed at 22'to form a seat for and in which slides the feeler member, to bedescribed.

An actuator is mounted on the carrier, and it is herein shown asan'elongated' arm 23, fulcrumed between the ears 18. on a'pin 24,

and having a short lug 25 depending below i the fulcrum, the actuatorextending forward above the carrier and projecting above the top of thestand 12, as shown clearly in Figs.

8 and 9.

The th rd member of the feeler device and what may be termed the feelerproper, is mounted on thecarrer and has "a limited movement relativethereto. and .by or through such movement-controls the actuator. 23.1-Herein the feeler is shown as an elongated bar 26, having a somewhatbroader head 27, which fits slidably in the seat 22 ofthe carrier-headand rests upon the bottom thereof, the body portion of the feelerbeingdisposed within the slot 19 and at its forward end resting on guide ribsor lec ges 28. (Shown in dotted lines, Fig. 4.) The .feeler is alsoslidably supported on the crossbar 20, Figs. 8v and 9, and is slightlyfor the purpose.

, The feeler-head 27 has an impinging face or edge 29 and a transverserecess 30 in its under side to receive the portion of the carrierhead 16beyond the opening or aperture 21, the fore-andeaft width. of the recess30 being such that a slight longitudinal movementof the feeler can'beeffected with relation to the carrier.

A light spring 31, seated in a socket 32 in the carrier cross-head 13,bears against a shoulder 33 on the front end ofthe feeler, the strengthof-the s ring being sufficient merely to project the eeler whenunopposed into the position shown in Figs. 4 and 8.

A positive cohnection is provided between the feeler and the actuator 23by introducing the lower end of the lug 25 between transverse ahutmentsor shoulders 34 on the body or shank of the feeler.

Owing to the eatdiflerence in lever-arms, comparing the ug 25 and theactuator 23, the slight forward movement of the feeler on the carrier issufficient to elevate the tip of recessed the actuator a considerabledistance above the top of the stand 12, as shown in Fig. 9.

By properly shaping the adjacent faces of the lug 25 and the rearmostshoulder .34 said faces come into parallel contact when the actuator iselevated, Fig. 9, or in inoperative position, thereby preventing saidactuator from being unduly elevated and acting as a limiting-stop forthe said actuator when it is moved into inoperative position.

-When the lay boxed in the shuttle-box 3, the feeler will entertheshuttle and its face 29 will impinge upon the filling, and. the feelerwill thereby first be moved forward upon and relative to the carrier forthe slight distance permitted by the clearance of the recess 30 in thefeelerhead. Then the continued forward movement of the lay will'moveboth feeler andbeats up and the shuttle is I carrier forward inunison'against the action of to position lnoperatively the actuator 23by swinging the-latter into the position shown in Fig. 9, andconsequently when the carrierbegins to move forward with the feeler theactuator is inoperative and so remains during that forward stroke. Onthe return stroke as the lay swings back the spring 15 returns orprojects the carrier rearward to the full extent of its movement, Fig.8, and as the filling recedes from the impinging face 29 of the feelerthe weight of the actuator and the stress of the light spring 31operates to reset tuator, as described, and then the feeler and feelerdevice.

carrier will move outward in unison, the feeler thus intermittinglyimpinging on and being moved by means within the shuttle, such meansherein being the filling; but manifestiy the amplitude offilling-induced movementof feeler and carrier will gradually decrease asthe filling diminishes and the distance between the barrel of thefilling-carrier and the surface of the filling decreases. This gradualand intermittent diminution in the amplitude of the stroke of thecarrier and feeler (movin in unison) proceeds until the filling in the suttle is substantially exhausted or exhausted to a predetermined extent.

Referring to Fig. 4, it will be seen that there is substantially thesame relative distance between the impinging faces 29 and. 17-

of the feeler and the carrier when the said members are normal asbetween the surfaces of the barrel and head 7 and 8 of the bobbin in theshuttle and that the face 29 of the feeler extends by that amount beyondthe face 17 of the feeler-carrier. The smaller part of thefilling-carrier is opposite the more extended part of the feeler deviceor barrel opposite feeler, while the larger part of the filling-carrieris opposite the less extended partviz., the impinging face 17 of theAspreviously pointed out, the construction'of both fillingcarrier andfeeler device can be made with the requireddegree of accuracy inthe.first instance, s9 that no adjustmentis left to the unskilled handlingof the loom operator in the mill.

Ve have herein embodied our invention in such a structure that as theamplitude of filling-induced movement of the feeler member graduallydecreases the distance between the impinging face 17 of thefeeler-carrier and some means within the shuttle gradually decreases, sothat when the desired or predetermined filling exhaustion is reachedsuch face 17 will impinge upon the means withinthe shuttle. In Figs. 1and 4 such means is the head 8 of the filling-carrier or bobbin, theslot 1 in the shuttle-wall being made long enough to permit readyentrance of the carrirr-head 16', with ample clearance. (See l i'g. 4..)As the face 17 is quite wide, a con siderable variation in the positionof the shuttle in the shuttle-box may occur without causing the part 8within the shuttle to move forward out of range of the impinging portionof the feeler-carrier. Furthermore, as the impingement of both feelerand feelercarrier is upon separate things, both Within the shuttle, andmaintaining a certain relation to each other, it will be manifest thatvariations in the lay-stroke will have no effect whatever upon theoperation of the feeler device. At the instant that the diminution inthe diameter of the yarn mass permits the feeler-head to extend so farinto the shuttle that there can be no filling-induced movement of thefeeler the latter remains dead, inert, or passive on the carrier, andthe actuator will remain quiescent and in its operative position, Fig.8. The feelenpreviously active and by its action positionmginoperatively the actuator and also maintaining the carrier passive, nowbecomes passive, while the carrier changes from a passive to an ac. tivecondition, for it immediately impinges upon the head-8 of thefilling-carrier and is moved' forward thereby as the lay completes itsforward beat, the carrier and actuator moving forward together as aunit. The feeler is of course moved forward with the carrier; but thefeeler is absolutely inert and non-contacting with the filling remainingon the barrel of the filling-carrier, the remaining filling beingindicated at f, Fig. 4. Such filling remainder may be of any desiredquan tity; but it is in practice at least suflicient to extend a coupleof times across the .lay to insurea complete pick of filling in thecloth after exhaustion indication and before filling replenishment,reducing the waste to the lowest possible degree.

The change in the operation of the loom is effected by or throughtheexhaustion-indicating mechanism with absolute promptness and precisionat the proper instant, and at such instant there is non-contactionbetween the filling and the feeler proper, or indeed, any part of thefeeler device. The operation of the latteris dependent solely upon thefilling-carrier in the structure so far described or on somethingclosely pertaining to the filling-carrier and within the shuttle, aswill be explained. There can be no premature change in the operation ofthe loom, however, for while there is sufficient filling within theshuttle to impart a movementto the feeler by impingement thereonsuchmovement will inoperatively position the actuator, so that the loomoperation cannot be changed until just exactly-the desired degree offilling exhaustion is reached. Until such time the feeler is primarilymoved by impinging on the filling, while a secondary movement of thefeeler-carrier-is effected through said feeler but when the latternoncontacts with the filling the feeler-carrier is moved immediately andprimarily.

Means for causing the forward movement of the operatively-positionedactuator to effeet a change in the operation of the loom will bedescribed; but as such means is substantially the same as shown anddescribed the stand 12, the cam-slot 39 in said ear, and

crumed on the stud 42.'

the controller for the transmitter may be and are all as in our patentjust referred to, the

as an arm 40, fulcontroller being shown The free end of the controllerpasses through the cam-slot 39,

under the guide 38, and across the top of" the stand 12, the end or foot43 of the controller extending into the operative path of movement ofthe actuator 23, the tip of the latter being beveled at 45, while therear 'edge of the root is notched at 44, Figs. 8 and 9. Nor mally thecontroller is in the low portion of the cam-slot 39, and if movement ofthe controller is effected toward the front of the loom it will actthrough the cam-slot to depress the adjacent end of the transmitter,rocking the latter on its fulcrum and movin the. latch (1- into positionto be engaged an moved by the actuator or weft-hammer W. No movement ofthe controller 40 can be el- "fected so long as fillin -induced movementof the feeler inoperative y positions the actuator with its shar enedtip above the foot 43 of the controll er, and when such tip passesforward beyond the notched edge 44 of the possibility cooperate with andmove the controller.

A spring 46 acts norma ly to hold thecontroller in the low or rear end of the cam-slot 39, locking thetransmitter in inoperative position.

In each of Figs. 4, 6, and 7 the filling is supposed to have beenexhausted to the predetermined extent, so that the other means withinthe shuttle is impinged on by the feeler-carrier or member of the feelerdevice which is not the feeler proper.
